Subject: [PATCH 1/3] opp: core: add regulators enable and disable
Date: Mon, 8 Jul 2019 16:11:38 +0200 [thread overview]
Message-ID: <20190708141140.24379-2-k.konieczny@partner.samsung.com> (raw)
In-Reply-To: <20190708141140.24379-1-k.konieczny@partner.samsung.com>
From: Kamil Konieczny <k.konieczny@partner.samsung.com>
Add enable regulators to dev_pm_opp_set_regulators() and disable
regulators to dev_pm_opp_put_regulators(). This prepares for
converting exynos-bus devfreq driver to use dev_pm_opp_set_rate().
